    I copied this idea from another forum member. Super easy to construct. Bought the Red LEDs and blue from Steve's LEDS per Turbos recommendation, and heat sinks from Turbo. Scratched the mesh up a bit but no mortar, and added a 2x2" seed screen from my dump bucket scrubber. The attached pictures are from 8 days of growth. after 24 hours the screen is already completely covered back up with algae. Scrubber is working like a champ. Last picture is a comparison of the first weeks growth of my DIY vertical compared with a weeks worth of my old Dump buckets style. Almost the same output after week #1!

    Fantastic comparison, thank you for sharing!

    Remind me, what are the dims of the waterfall and the dims of the dump bucket? IIRC that Inland Aquatics dump-bucket scrubber was 8x12?

    The dump bucket style screen is a 9 x 20, although I would say I don't have algae growing on the last 3" of it. Probably a 10" x 17" area of growth. I cut the side too narrow so I have about 1" all the way down the side that grows to the bucket itself I must scrape off each week.

    the reason I'm missing 3" of growth on the end is that is the length of the mars aqua I put above it. It is like a line in the sand where algae quits growing well at the edge of light. Pretty amazing how much lighting is required for algae to grow, at least GHA.

    the GHA grows over the top of the red turf alga seed screen within 36 hours each week. Ive already completely coated the white mesh again within 24 hours of the vertical, for being less than two weeks old it has exceeded my expectations compared to other DIY ATS posts I have seen. I imagine that has to do with the seed screen though. I scraped it pretty rigoursly as well when I cleaned it as I had the seed screen to replenish if needed and a lot of the algae was difficult to remove. I removed the seed screen as well from the vertical before putting it back into service.

    While yes this is going to work well, I still would rather have a professional model that you make. Algae goes out the drain pipe into the tank if I don't use a sock, and I'm guessing this is after maybe 2-3 days. I made a false bottom but apparently it is getting around that, and I also can't look inside of the box to see what is going on very well due to the PVC construction.

    Not sure of anyway to keep algae from growing into the groove I cut in the PVC either when using regular PVC pipe. I will definitely be looking forward to when my time on the waiting list arrives so I can upgrade to a more well built professional unit.

    At this time I plan on continuing to use both scrubbers until I get yours in and it is established. I have some very healthy fish in the tank and since my phosphates have lowered dramatically once they started growing GHA Ive added some rescue frags from Inland right before they closed. Very inexpensive stuff that won't bother me if it doesn't make it. But so far seems to be flourishing.

    My DIY scrubber screen I think is 6X7" double sided and the dump bucket is 9x17 single sided. Im feeding a total of around 6 cubes a day to the fish. Not sure where this puts me if I could be feeding more or if I am over doing it?
